Dear all,
I recently bought the MKRGSM 1400 in the kit with Arduino antenna and Arduino sim card. I'm doing the tutorial on the project hub for the "Securely Connecting a MKR GSM 1400 to Google Cloud IoT Core" . I registered and configured an IoT core project on the GCP platform as it was well explained on the tutorial. But when I go to upload the sketch and open the serial monitor I get the right connection to the network however it cannot connect to the MQTT broker and therefore to the project on GCP. remains as attempting.
I can't recognize what the problem is, if it is a hardware issue (the MKR card uses a 3.7v 1200mAh Lp battery) or if there is something wrong with the GCP. I am desperate because I can't get over it. Someone had the same problems or could help me. Thanks.
